A cruise up the Yirinni River (Hunter River) this morning to see the mangroves – the apple mangrove which has a big trunk and the grey mangrove which is more like the ones we are used to, with their aerial roots. A tranquil cruise in the morning light with great reflections in the water. Bird calls but not many views except for a magnificent pair of sea eagles. A moon jellyfish bobbed in the water. A nursery for the crocs.

Sandy described the water as suspended solids and you can see why.

In the afternoon a trip over to Bigge island to see the Wandjina Rock Art and Cathedral Cave round the corner with its huge slabs of sandstone. The roof on this Cathedral had just proved too heavy and came crashing down on its side. The stones around eroded by sea and wind to earthy columns, molars, toes, crocs and even a bust of Queen Victoria with an osprey nest on her head.
